What it means
F35875 means that a Terminal Module (TM) has told the Control Unit, over DRIVE-CLiQ, that its supply voltage has failed. The manuals give this code the fault cause 9 (= 09 hex): the power supply voltage for the components has failed. The two manuals describe the code identically for the Terminal Module, so the behaviour below applies to every drive object it is raised on.
Why it appears
- The DRIVE-CLiQ communication from the DRIVE-CLiQ component involved to the Control Unit signals that the supply voltage has failed.
- Fault cause 9 (= 09 hex): the power supply voltage for the components has failed.
- The manual points at the supply side of the component: an interrupted cable or poor contacts in the power supply voltage wiring, or a power supply that is not dimensioned for the DRIVE-CLiQ component.
What to check
- Carry out a POWER ON (switch-off/switch-on).
- Check the power supply voltage wiring for the DRIVE-CLiQ component — interrupted cable, contacts.
- Check the dimensioning of the power supply for the DRIVE-CLiQ component.
Reading the message value
- The message value carries two items: the component number (%1) and the fault cause (%2).
- The manuals code the value held in r0949/r2124 as 0000yyxx hex: yy = component number, xx = error cause.
- For F35875 the fault cause is 9 (= 09 hex), the failed power supply voltage for the components.
Parameters the manual names
- r0949 — fault value: read the coded message value of F35875 (component number and fault cause) here.
- r2124 — alarm value: the manuals name it alongside r0949 as the register in which the coded value 0000yyxx hex is stored.
Acknowledging and restarting
The fault must be acknowledged before the drive can be restarted. The manual's remedy begins with a POWER ON (switch-off/switch-on); once the supply voltage problem is corrected, this also clears the fault.
The same on every family
Every manual that describes F35875 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

| S120, S150 | OFF1 (OFF2) | IMMEDIATELY | Supply voltage fault (undervoltage) (3) | Terminal Module (TM) | SINAMICS S120, S150 List Manual · p. 3238 |
| G130, G150 | OFF1 (OFF2) | IMMEDIATELY | Supply voltage fault (undervoltage) (3) | Terminal Module (TM) | SINAMICS G130, G150 List Manual · p. 1900 |

Questions technicians ask
What does fault F35875 mean on a SINAMICS drive?
A Terminal Module has reported over DRIVE-CLiQ to the Control Unit that its supply voltage has failed. The fault cause is 9 (= 09 hex): the power supply voltage for the components has failed.
How do I fix fault F35875?
Carry out a POWER ON (switch-off/switch-on), then check the power supply voltage wiring of the DRIVE-CLiQ component for an interrupted cable or bad contacts, and check the dimensioning of its power supply.
How is the message value of F35875 decoded?
In r0949/r2124 the value is coded 0000yyxx hex, where yy is the component number and xx the error cause. For this code the fault cause is 9 (09 hex).
Which component reports F35875?
The fault comes from a Terminal Module (TM) — the manuals list TM120, TM150, TM31 or TM41 among the affected drive objects — whose supply voltage has failed.
